I'm going to post this to the tracker, but I thought I'd post here as well to talk about it & get people's reaction.

I think it would be a cool feature to be able to 'automagically' guess the meta data for a book in a similar way that Calibre fetches it for boos where the ISBN has been entered. I've been looking at the isbndb page, trying to work on scripts to generate the proper data, and here's what I've done:

I have a file called "Oedipus The King.lit", and I strip off the extension and build the search query:

I don't think that it would be too hard to add this to the existing meta data search tool, since it already parses out this data when there are multiple entries for a single ISBN. This has the benefit of being able to search when the ISBN may not be known, and the user is then able to choose the best match.

Another thing that may be good is to have an option to auto search on import of a book. If the ISBN is there, search from that; else search based on file name (or other present data).

I think the ability to get the extra info by the fetch metadata is great. So far I haven't been able to change/add this info to ebooks that are already in sony format. Could you give an old man a clue...

You can't add arbitrary metadata to ebooks in the SONY format (the reader software doesn't support it). When you use calibre to upload, the extra metadata is uploaded alongwith the ebook. You can only change title and author for ebooks already on the reader. Do this by double clicking on the ebook name.
